WALL-TIE,

Specification of Letters Patent.

Patented March 27, 1906.

Application filed December 7. 1905. Serial No. 290,664.

-To all whom it may concern:

at Middletown, Butler county, Ohio, (post-' office address No. 539 East Tlnrd street, Middletown, Ohio,) .have invented certain new and useful Improvements in Wall- Ties, of which the following is a specification.

This invention, pertaining to improvements in wall-ties for employment in mortarjoints for the purpose of more perfectly bonding together the component members of a wall structure, will be readily understood from the following description, taken in connection with the acoompan 'ng drawing,

which is a perspective view 0 my improved wall-tie.

In the drawing,.1 indicates the tie as a whole?l the same being in the-form of a strip of rat er thin sheet metal, preferably galvanized 2, corrugations extending across the tie from edge to edge, the series of corrugations beginning at one end of the tie and extending umnterruptedly to the opposite end of the tie or of such'portion of it as is to find embedment in the joint in which the tie is to be employed; and 3, a continuous longitudinal ser1es of perforations extending through the corrugated portion of the tie, these perforations having greater length than Wldthj their major dimensions being crosswise of the tie.

The holding-power of the tie comes from the intermembering of the corrugations with the mortar and also from the keys formed by the mortar within the perforations, the perforations permitting mortar to pass through the tie while it is bemg positioned. The corrugated and perforated features being'uniformly characteristic of the entire length of the embedded tie permits the tie being usefully positioned without special need for accuracy, all embedded portions of the tie being of equal efficiency. Furthermore, any de-' sired portion of the tie may be cut ff without impairing the efficiency of the remaining portion. The corrugations produce valleys alternating with ridges, the ridges on one side of the tie coming opposite the valleys on the other'side. The perforations are through the corrugations and place each valley on one side of the tie in communication with the contiguous valleys on the opposite side. The result is that the mortar-ridge formed by and keying bonded to the two mortar-ridges formed by and keying into the contiguous valleys on the op ositesideofthe tie.

claim As an article of manufacture a wall-tie for embedment in a mortar-joint, formed of a strip of sheet metal provided with a continuous ongitudinal series of transverse corruga tions forming opposin ridges and valleys and with a contlnuous ongitudinal series of perforations through the corrugations and placing each valley incommunication with two opposing valleys the erforations-,having greater length than widt and having their major dimensions parallel with the corrugations.
